WILLIAM H. DAVIS, OF VERONA, MISSISSIPPI.

DRIVING MACHINERY FOR COTTON-GINS, MILLS, 84C.

SPECIFICATION forming part of Letters Patent No. 277,240, dated May 8, 1883.

To all whom it may concern:

Be it known that I, WILLIAM H. DAVIS, of Verona, in the county of Lee and State of Mississippi, have invented certain new and useful Improvements in Driving Machinery for GottonGins, Mills, &c.,'of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding-parts in both the figures.

Figure 1 is a plan view of my improvement, partly in section and parts being broken away. Fig. 2 is a sectional side elevation of the same, taken through the line a: m, Fig. 1.

The object of this invention is to improve the construction of the driving machinery for cotton gins for which Letters Patent No. 257,667 wereissued to me May 9, 1882, in such a manner as to make it more simple in construction and cause it to operate with less I friction.

The invention consists in the combination, with the power-wheel and the counter-shaft pulley of a driving machinery for cotton-gins, of a guide-pulley and a sliding frame carrying the said guide-pulley, whereby the drivingband will be made to pass squarely upon the counter shaft pulley, and the tension of the said driving-band can be readily regulated.

The invention also consists in the combination, with the power-wheel, of guide-pulleys, whereby the driving-band will be made ,to pass to and from the power-wheel in a horizontal position, as will be hereinafter fully described.

A represents the frame, which may be the frame of a gin-house, or a frame built expressly to receive the driving machinery.

B is the power-wheel, which is attached to or framed into a vertical shaft, 0. Thejournals of the shaft 0 revolve in hearings in the frame A, and to the lower part of the said'shaft are rigidly attached the arms D, to which the horses or mules are attached. The rim of the wheel B is grooved to receive the rope or band F, which also passes around the grooved pulley Gr, attached to the countershaft H.

The counter-shaft H is placed in a horizontal position, is journaled to the frame A, and to it is attached the pulley I, around which passes the band J. The band J also passes around the pulley K of the cotton-gin L, or other machinery to be driven.

Application filed November 14, 1882. (N 0 model.)

The driving-rope F passes to the powerwheel B in a direction'tangent to the said wheel, as shown in Fig. 1, and as it passes to and from the said wheel it is supported in a horizontal position by the horizontal guidepulleys E, which are pivoted to the frame A or other suitable support. As the rope F passes from the power-wheel B to the pulley G it passes around the guide-pulley M to bring the said rope into position to pass squarely upon the said pulley G. The pulley M is journaled in a vertical frame, N, which slides in groove ina vertical stationary frame, 0, connected with the frame A, so that the frame N and pulley M can be readily adjusted to regulate the tension of the driving-band F. The frame 0 can be secured in place, when adjusted, by pins, Wedges, or other suitable means.

With this construction the driving mechanism is brought close to the side of the house or frame A, so as to leave the greatest possible amount of available room, and the said mechanism is so arranged as to Work with the least possible amount of friction.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- '1. In driving machinery for cotton-gins, mills, 850., the combination, with the horizontal drive-wheel B, vertical pulley G, and belt F, of the guiding and tension pulley M, arranged upon an adjustable support, N N, and adapted to bear on the belt intermediately between the wheel and pulley G, whereby acommon means is provided to guide the belt or change its direction and to regulate its tension, as set forth.

2. In driving machinery for cotton-gins, mills, 850., the combination, with the horizontal drive-wheel B, vertical pulley G, and belt F, of the guide-pulleys E, arranged to guide the belt on said wheel, and the tension and guide pulley M, arranged upon an adjustable support, N, substantially as and for the purpose set forth.
